Would love to ask him if there is ever a moment when he thinks “this was a bad idea.”

I worked on a construction site where all the workers are walking around at 35 feet height on inches wide walls. No one bats an eye. Then one day a guy goes to slide down the flange of a column like usual and slips. His feet hit the ground , legs buckle hard, and his knees shatter against the steel flange the column. He screams and writhes.

Every other worker on the walls lost their nerve in an instant and had to be picked up in cherry pickers.

Or maybe he’s like Karina Hollekim, seemingly totally unbothered. This is a great doc, btw:
